I've been searching for an hour on here and can't find a straight up answer. I need to find a switched 12v power source in the dash area. I'm adding a backup cam to my factory headunit, but can't find a good switched power source. I have tested many wires with my meter but none have panned out. None of the wires on the radio power harness had a switched 12v function. I have the factory navi headunit with monsoon sound system.
I read where someone suggested using the red/white wire in the radio power harness. There is no red/white wire on my radio harness.
Please help, my dash is torn apart until I solve this dilemma.

thank you in advance!

 

Try one of the wires for the trailer brake controller up by the gas pedal

 

Or use your meter and find a spare switched 12vdc on the fuse panel. My backup camera utilized the power from the reverse light which only supplies 12vdc when in reverse. Why don't you use that?

 

In case anyone cares, I found a +12v switched (acc) wire under the emergency brake area. There is an unused blue harness with two wires that are both +12v switched.

 

Thanks, I was just looking for the same thing!
